You can put both wires that now go to the two posts on your amp to the "+" post on the volt meter. That will retain the circuit so everything works. Some volt meters are internally grounded and have one post, if there are two, ground the "-" one, and you are in business.

Most amp gauges I've worked with were wired with 12 gauge wire and either terminal on a volt gauge does not have sufficient length to attach 3 wires especially if two of them are 12 gauge. IMHO there are three ways to solve the problem. 1. take the two wires from the amp gauge and bolt them together and tape the connection. 2. Cut the terminals off and solder the two wires together with heat shrink over the connection. 3. Eliminate the wires totally from under the dash using a diagram from a later vehicle that uses a volt gauge instead of an amp gauge.

There won't be three wires, just the two that used to go to either side of the amp gauge. You can bolt them together and run another wire to the voltmeter if that's easier.

Thanks guys. Looks like the volt gauge will be simple. I'm still not sure if the pcv valve will be good enough. I really don't want to run breathers on the valve covers if i don't have to.

The PCV will need a fresh air source somewhere on the engine.........preferrably the valve cover that does not have the PCV in it.

I have my fresh air source on the oil fill tube in the intake...not a ideal spot ,but better than nothing.

I prefer the old school look of the oil filler tube and as soon as i find an Edelbrock C3B-X or C4B intake manifold i'll swap out the Weiand i have on it now.
